Hello !

And now i have problem with my Windows 8.1 computer cant surf on any browser because
off a security certificate issued by Adguard......what the hell... is happening :mad:

If i uninstall Adguard everythings okey....
Seems to be a lot off problems with this new version ... on my Vista 32 its impossible to install. And now this certificate
problem on Windows 8.1 64 bit. Says Adguard certificate is untrusted.

For the time the program is unusable on all my computers this sucks......

Yes Andrey i completely wiped everything also settings.
Maybe certificates generated after update were invalid and wiping them allowed AG to re-generate them.

It's hard to say now why they were invalid.
